get him to a dermatologist.i was born was psoriasis, and grew up with a scalp covered in thick scaly patches.things that have worked: medicated creams (amcinonide, which helps more with the redness and irritation, and dovonex, which helps with the dryness and scales), and moisturizers. for the scalp and face, i'd recommend some kind of oil, either jojoba or almond. and don't pick at it!
